We have various topical threads, e.g. The Food Thread, Best Songs Ever, How does your Garden grow?, etc, so I thought a cycling thread would be in order. This past summer, our family invested in some new bicycles for family cycling outings. We've frequented a local railtrail. I have a 30+ year old 12-speed, but my new bicycle is a 14-speed with conventional lever gear shifters, as opposed to modern thumb shifters or rotational/rotary shifters on the handlebars. My wife and son got 21-speed bicycles. I was also looking for a place to put news of a new innovation - the Copenhagen Wheel. http://digg.com/video/mit-actually-reinvented-the-wheel http://senseable.mit.edu/copenhagenwheel/ http://senseable.mit.edu/copenhagenwheel/wheel.html https://www.superpedestrian.com/ Power assist and regenerative breaking. Very cool!
